Buying Guide: Key Purchase Considerations
What size do I need? Aim for a unit that matches room size (typically 600–900 sq ft per 12k BTU, but consider climate and insulation). A mismatched size reduces efficiency and comfort.
How important is energy efficiency? SEER2 ratings indicate potential energy savings. Higher ratings generally reduce operating costs over time, especially in spaces with year-round use.
What about noise? Look for units with low dB in sleep or mute modes for bedrooms and nurseries. Inverter-driven compressors typically run more quietly than traditional models.
What features add value? Remote or app control, self-cleaning cycles, air-swing direction, and timers help tailor comfort and reduce manual adjustments.
Is installation straightforward? Some models ship as pre-charged and include installation kits. If you’re unsure about refrigerant handling or wall mounting, consult a pro to ensure proper charge and sealing.
